Schematic for the analog sensorsTest Step 1. Inspect the Electrical Connectors and Wiring
Set the engine control to the OFF/RESET mode. Remove the electrical power from the engine.Note: For the following steps, refer to Troubleshooting, "Inspecting Electrical Connectors".
Illustration 2 g01085914
Terminal box for the master ECM (1) J1/P1 connectors for the master ECM (2) J7/P7 connectors for the wiring to the analog sensors
Thoroughly inspect the following connectors:
J1/P1 connectors
J7/P7 connectors on the terminal box
Check the torque of the allen head screw for the ECM connector. The proper torque is 6 1 N m (55 9 lb in).

Harness side of the P7 connector (P7-C) Signal for the engine coolant temperature (P7-F) Signal for the inlet manifold air temperature (P7-G) Signal for the filtered engine oil pressure (P7-J) Signal for the engine oil temperature (P7-U) Signal for the unfiltered engine oil pressure
Perform a 45 N (10 lb) pull test on each of the wires that are associated with the circuit for the analog sensors.

Check the harness and wiring for abrasion and for pinch points from each analog sensor to the master ECM.Expected Result:All connectors, pins, and sockets are connected properly. The connectors and the wiring do not have corrosion, abrasion, or pinch points.Results:
OK - All connectors, pins, and sockets are connected properly. The connectors and the wiring do not have corrosion, abrasion, or pinch points. The components are in good condition with proper connections. Proceed to Test Step 2.
Not OK - At least one of the connectors, pins, and/or sockets are not connected properly. At least one of the connectors and/or the wiring has corrosion, abrasion, or pinch points.Repair: Perform the necessary repairs and/or replace parts, if necessary. Stop.Test Step 2. Check for Diagnostic Codes for the Power Supply
Connect Cat ET to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools".
Restore the electrical power to the engine. Set the engine control to the STOP mode.
Observe the "Active Diagnostic" screen on ET. Allow a minimum of 30 seconds for any codes to activate. Look for these codes:
262-03 5 Volt Sensor DC Power Supply short to +batt
262-04 5 Volt Sensor DC Power Supply short to groundExpected Result:There are no active "5 Volt Sensor DC Power Supply" diagnostic codes.Results:
No codes - There are no active "5 Volt Sensor DC Power Supply" diagnostic codes. Proceed to Test Step 3.
Active code - There is an active "5 Volt Sensor DC Power Supply" diagnostic code. This procedure will not work when this type of code is active.Repair: Refer to Troubleshooting, "+5V Sensor Supply".If necessary, return to this functional test in order to troubleshoot the analog sensor after the "+5 V Sensor Supply" diagnostic code has been resolved. Stop.Test Step 3. Check for Active Analog Sensor Diagnostic Codes
Observe the "Active Diagnostic" screen on Cat ET. Wait at least 30 seconds so that any codes may become activated. Look for the codes that are listed in Table 1:
